AUTRONICA FIRE AND SECURITY
BHH-31A/M
SMOKE DETECTOR
ID-NR: B06230710
1175-CPD-015
The Autronica BHH-31A/M is an optical smoke detector designed for integration into marine fire alarm systems. Operating on the principle of light-scattering detection, it identifies the presence of smoke particles in the protected space and triggers an alarm signal to the connected fire detection panel. As a core component of a shipboard fire alarm system, this detector plays a critical role in early fire warning, helping protect crew, cargo, and vessel structure in line with SOLAS fire safety requirements.
Key Features
✓ Optical detection principle uses light-scattering technology to identify smoke presence reliably in protected spaces.
✓ Exact electrical ratings and response thresholds are subject to confirmation against the installation configuration and applicable panel documentation.
✓ Designed for compatibility with Autronica fire detection systems; system panel compatibility should be verified against the specific installation prior to fitting.
✓ Suitable for installation in accommodation, machinery, and service spaces onboard vessels where smoke detection coverage is required under fire safety regulations.
✓ Replacement of this detector supports continued compliance of the vessel’s fire detection loop; routine servicing and periodic testing are recommended per the system maintenance schedule.
Marine Applications
✓ Cargo vessels and bulk carriers requiring SOLAS-compliant fire detection coverage across accommodation and service spaces.
✓ Offshore support vessels and platform supply vessels where fire alarm integrity is essential to safe operations.
✓ Passenger ferries and cruise ships with large accommodation zones requiring distributed optical smoke detection.
✓ Naval and government vessels operating fire alarm systems that demand proven, type-approved detection components.
✓ Tankers and chemical carriers where early smoke detection in non-hazardous spaces forms part of the overall fire safety strategy.
